In the private sector, an increasingly small one. The issue of unions is really important in the public sector because I think private sector unionism is at an all-time low in the United States, but public sector unionism continues to rise. It artificially increases the cost of labor for governments which means tax payers. For example, a Stanford University found that California's unfunded pension liability is about $500 million (about 6 times their annual budget). They're already inherently parasitic in that a government employee can't exist without the tax payer who is the host. That's not a value judgment in saying that they don't produce anything of value, there's simply a cost associated with a government employee that's different than their private sector counterpart.
